MANG-ER.

Specification of Letters Patent.

Patented Dec. 15, 1914:.

To all whom it may concern:

Be it known that we, HENRY L. Fnnnis and HOWARD J. FERRIS, citlzens of the Unlted States, residing at Harvard, in the county of McHenry and State of Illinois, have invented a new and useful Improvement 1n Mangers, of which the following is a specification.

Our invention relates to certain new and useful improvements in mangers and is fully described and explained in the specification and shown in'the accompanying drawings, in which Figure 1 is a section on the line 1 of F 1g. 2, that is a view showing everything except the forward wall of the manger in side elevation; Fig. 2 is a sect-ion on the line 2 0f Fig. 1, this view thus showing the ma or parts of the structure intop plan; Fig. 3 is a section on the line 3 of Fig. 2 and on a somewhat larger scale; and Fig. a is a section on the line 4: of Fig. 3.

Referring to the drawings, 6 is the curb of the stall to which the manger is applied, the stall proper being to the rear thereof and the floor in front of the curb being provided with a trough 7 forming the bottom of the manger.

8 are manger-partitions, to the forward edges of which is attached a manger-front 9.

As a measure of convenience the mangers are made in separate units, preferably one unit for each three stalls, as herein shown, so that each manger-front is attached to four of the partitions 8, one at each end and two intermediate. To stifien each unit thus formed, an angle-iron 10 is extended along the upper forward corner of the unit, the angle of said angle-iron extending forwardly, whereby one flange is in the plane of the manger-front 9 and the other flange extends diagonally upward and backward, as shown.

Mounted upon the curb 6, opposite the division lines between the stalls are castings 11, each of which has adjustably attached to it the lower corners of the two adjacent stall-fronts 12, the said stall-fronts carrying, in the usual manner, stanchions which are shown in section in Fig. 2 and designated 18. Each stall is thus provided with an adjustable stanchion-carrying frame of the type broadly claimed in our Patent No. 1,066,194, and having the advantages therein set forth.

IIeretofore it has been the practice when using a pivoted manger to carry the same upon the framework of the stall, but when the adjustable stanchion-carrying stall-front 1s used to secure the manifest advantages of that construction, it is a matter of considerable difficulty to supply a manger-sup port adaptable for stalls of all types, since some stalls have practically no stationary framework, and in any event the stationary parts upon which the adjustable front is mounted vary so much in type as to necessitate special manger-supports for the special types, if any effort is to be made to support the manger from the framework. However, whatever be the type of stall construction adopted, there is provided inrall cases, for the adjustable stanchion-carrying front'as used in accordance with our designs a casting set in the curb substantially similar to that herein shown, and designated by the numeral 11. This we utilize as the mangercarrying means, thereby securing a device which is thoroughly efiicient whatever he the type of stall construction.

Each of the castings 11 is slotted at 14 and to its upper surface is bolted a plate 15 having an upwardly projecting flat ear 16 lying" in a plane longitudinal of the stall. Embracing the rear edges of the manger-partitions 8 are hinge-members 1'7 each of which has at its rear end two cars 18 embracing the ears 16 and pivoted thereto, so that the manger can be swung up from the position shown in solid to that shown in dotted lines in Fig. 1. The upward swinging of the manger is limited by engagement of the angle-iron 10 with whichever of the stallfronts in the series happens to be adjusted in the forwardmost position.

For the purpose of assisting in raising the manger and holding it in its raised position,

the spring mechanism shown in provided at one or more of the. pivots. We prefer to employ spring mechanism only at the intermediate pivots of the manger, leaving the end pivots as shown without the spring means. In the structure illustrated here, the springmeans is shown only at intermediate struction of the spring means. The castings V 11 are provided with rearwardly extending ears 19, which afford pivotal support to a shaft 20 having a squared intermediate por tion adapted to engage the inner end of a spring 21. v

The opposite end of the spring is hooked to engage a pin 22 adjustable into any of a series of holes 23 inthe ears 19, whereby the spring tension can be varied. The shaft 20 has projecting from-it radial arms 24 con-v nected by means of a link 25 hooked over said arms, with the hinge-member 17, the pivot of the link'thereon being so placed that when the manger is down the link lies quite close to the-pivot of the manger. In other words, when the manger is down the spring tension is along a line close to the dead center, and thespring therefore exerts but slight elevating force. As the manger rises, however, the efficiency of the spring increases, so that when in its upper position the manger is held firmly against displacement.

The present device is advantageous, not only for the reasons already pointed out, but further because of the simplicity and efficiency of the spring means. The spring means is readily adjustable to difl'erent degrees of tension. Furthermore when the manger is erected by unskilledhelp, as it often is, the spring need not be under tension. In devices for a similar purpose here.- tofore employed, the spring has been under continuous tension, or, if not, it was a matter. of greatest difiiculty to place it under tension without special tools. With the present device the several parts are set together without any tension on the spring, the wrench is placed on the squared outer end of the shaft 20, which is rotated in a direction to throw the arms 24 far enough" forward, against the tension of the spring for the link 25 to be hooked over them.

This will preferably occur when the manger is in elevated position. Any irregularities in the tension of the springs can be taken up by the adjustment shown.

It ,ismanifest that the present device is capable of considerable variation without departing from the spirit of our invention, as we do not intend to limit ourselves to the specific form herein shown, except as pointed out in the. following claims, in which it is our intention to claim all the novelty inherent in the device as broadly as is per front of the same, a casting carried by the -curb, a manger recelving pivotal support from the casting, and means carried by the casting for exerting elevating pressure on themanger.

3. In combination, a curb, a trough in front of the same, a'casting, a member longitudinally adjustable on the casting, a manger pivoted to said member, and spring means'connecting the manger and casting to elevate the manger.

4. In combination, a curb, a trough in front ofthe same, a casting mounted on the curb and having rearwardly extending ears, a coiled spring carried between said ears,

means for locking one end of the spring in stationary position,and a link having means of connection with the opposite end of said spring at one end, and at the other engaging the manger. i

5. In combination, a curb, a trough in front of the same, a casting mounted on the curb and having rearwardly extending ears, a coiled spring carried between said ears,

means for lockingone end of the spring adjustably-in stationary position, and a link having means 'of connection with the oppo-- site end of said spring at one end, and at the otherengaging the manger.

6. In combination, a curb, a trough in front of the same, a-casting mounted on the curb and having rearwardly extending ears, a shaft mounted in said ears and carrying a coiled spring, radial arms on the shaft, a

manger receiving pivotal support from the casting, and a llnk connecting the outer end of sald arms with the manger.

7. In combination, a curb, a trough in front of the same, a casting mounted on the curb and having rearwardly extending ears,

a shaft mounted in said ears and'carrying a coiled spring, radial arms on the shaft, a manger receiving pivotal support from the casting, and a link'connecting the outer end of said arms with the manger, andmeans for adjusting the outer end of the spring to secure variations in the tension thereof.
